Urge the IDA and all relevant institutions to adopt a true (i.e., scientific) definition of Light pollution. Light added artificially outdoors at night is a serious pollutant.
Urge all legislative bodies to allow no light going
horizontally or upwards from outdoor lighting.
Any arguments against it have been proven false by science long ago
and by the excellent experience from countries with such legislation:
Slovenia and most of Italian provinces.
And we recommend to switch off the lights or at least dim them 3×
or more when there are no or almost no users of them.
Stress that any surfaces with luminances 10× or more strong than the road luminance, if in the field of view, are denying the purpose of outdoor lighting, are uncomfortable for people and dangerous to traffic. This concerns advertising and building illumination, among others.
Feel that having artificial window illuminance of windows from outside at night lower than 0.2 lx is a basic human right.
